What struck me was that IQ was not the only
between my best and my worst students. Some of my strongest performers did not have stratospheric IQ scores. Some of my smartest kids weren't doing so well. And that got me thinking. The kinds of things you need to learn in seventh grade math, sure, they're hard:
, decimals, the area of a parallelogram. But these
are not impossible, and I was firmly
that every one of my students could learn the material if they worked hard and long enough.
